hyperlinked haskell 98 grammar

Hi, I was improving my Haskell knowledge lately and I created a small dhtml application which allows browsing of Haskell 98 grammar. I contains both forward and backward hyperlinks. By backward hyperlink I mean that you can click on an a production head and you get a popup list box where you can navigate to any production using the nonterminal. If you like it please save and use your local copy since the server cannot handle much load. http://www.hck.sk/users/peter/ Peter.
